Answer:
1
answer is D
Step-by-step explanation:
we must calculate it from this equation :
x³ -9x²+27x-25 then
C = conference room capacity
we can write something along the lines of C < 100, namely C can hold is less than 100.
for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³
Answer:
If it is ax^2 + bx + c = 0 then it is a quadratic equation
